Subject: m68k: Remove BKL from rtc implementations
X-Git-Tag: v2.6.35-rc1~529^2~12
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b1f3bb494e8acddeb972331c2ac642b3c7bceeb9;p=pandora-kernel.git

m68k: Remove BKL from rtc implementations

m68k does not support SMP. The access to the rtc is already serialized
with local_irq_save/restore which is sufficient on UP.

The open() protection in arch/m68k/mvme16x/rtc.c is not pretty but
sufficient on UP and safe w/o the BKL.

open() in arch/m68k/bvme6000/rtc.c can do with the same atomic logic
as arch/m68k/mvme16x/rtc.c
